Kinematics of AGN and Quasar Jets
K. I. Kellermann, M. L. Lister, D. C. Homan +3
The major multi-epoch VLBA programs are described and discussed in terms of relativistic beaming models. Broadly speaking the observed kinematics are consistent with models having…
SPITZER SAGE Observations of Large Magellanic Cloud Planetary Nebulae
J. L. Hora, M. Cohen, R. G. Ellis +14
We present IRAC and MIPS images and photometry of a sample of previously known planetary nebulae (PNe) from the SAGE survey of the Large Magellanic Cloud (LMC) performed with the S…
The Frequency of Mid-Infrared Excess Sources in Galactic Surveys
B. Uzpen, H. A. Kobulnicky, A. J. Monson +27
We have identified 230 Tycho-2 Spectral Catalog stars that exhibit 8 micron mid-infrared extraphotospheric excesses in the MidCourse Space Experiment (MSX) and Spitzer Space Telesc…
Detection of a massive dust shell around the Type II supernova SN 2002hh
M. J. Barlow, B. E. K. Sugerman, J. Fabbri +11
Dust emission from the Type II supernova SN 2002hh in NGC 6946 has been detected at mid-infrared wavelengths by the Spitzer Space Telescope from 590 to 758 days after outburst and…
Discovery of a New Low-Latitude Milky Way Globular Cluster using GLIMPSE
Chip Kobulnicky, A. J. Monson, B. A Buckalew +28
Spitzer Space Telescope imaging as part of the Galactic Legacy Mid-Plane Survey Extraordinaire (GLIMPSE) reveals a previously unidentified low-latitude rich star cluster near l=31.…
The Giant Pillars of the Carina Nebula
J. M. Rathborne, K. J. Brooks, M. G. Burton +2
Results are presented from a multi-wavelength study of the giant pillars within the Carina Nebula. Using near-IR data from 2MASS, mid-IR data from MSX, 843MHz radio continuum maps…
The dual dust chemistry - binarity connection
Orsola De Marco, A. F. Jones, M. J. Barlow +1
Accumulating evidence points to a binary nature for the Wolf-Rayet ([WC]) central stars, a group that constitutes about 15% of all central stars of planetary nebula. From ISO obser…
Photodissociation regions and star formation in the Carina Nebula
J. M. Rathborne, M. G. Burton, K. J. Brooks +3
We have obtained wide-field thermal infrared (IR) images of the Carina Nebula, using the SPIREX/Abu telescope at the South Pole. Emission from poly-cyclic aromatic hydrocarbons (PA…
The Formation and Evolution of Planetary Systems: SIRTF Legacy Science in the VLT Era
M. R. Meyer, D. Backman, S. V. W. Beckwith +20
We will utilize the sensitivity of SIRTF through the Legacy Science Program to carry out spectrophotometric observations of solar-type stars aimed at (1) defining the timescales ov…
The complete ISO spectrum of NGC 6302
F. J. Molster, T. L. Lim, R. J. Sylvester +6
We present the combined Infrared Space Observatory Short-Wavelength Spectrometer and Long-Wavelength Spectrometer 2.4--197 micron spectrum of the Planetary Nebula NGC 6302 which co…
Gas metallicities and early evolution of distant radiogalaxies
M. Villar-Martin, R. A. E. Fosbury, J. Vernet +3
By modeling the rich emission line spectra of a sample of high redshift (HzRG, z\sim 2.5) radio galaxies we find that solar and supersolar metallicities are common in the extended…
Structure in the First Quadrant of the Galaxy: an Analysis of "TMGS" Star Counts using the "SKY" Model
P. L. Hammersley, M. Cohen, F. Garzon +2
We analyse the stellar content of almost 300 deg^2 of the sky close to the Galactic plane by directly comparing the predictions of the SKY model (Cohen 1994,1995; Wainscoat et al.…
